Your point was to nitpick about the scale of the diagram. Euclid didn't even understand the diagram.
No, after that point I quite reasonably pointed out that a ray from the Sun appearing to come from the ground would need to follow the same path as a ray from the ground itself, meaning that the sunlight would be bending
through the ground. So either you are suggesting that the Earth is transparent, or this phenomenon would not be observed.
We all know you don't really believe it anyway as you have admitted the earth is not flat.
No, what I said is that I don't believe the Earth to be flat.
If you can supply some experimental evidence of light being bendy without reference to the surface of the earth then go ahead. You won't be able to do it of course, whereas we can supply a shedload of evidence that light travels in straight lines without bending, and we can do it without using the earth's surface as a reference measure.
Show me one experiment which shows that light travels in straight lines.
